Abstract
The invention discloses a machining method for an automobile rectifier, which includes the steps: (1) placing connecting sheets on a sintering fixture, smearing welding paste and then placing a tube core; (2) smearing spot welding paste on a welding surface of the tube core and placing a positive or negative plate into a furnace for sintering; (3) detaching a mould after sintering, performing appearance test after discharge and then testing the plate; (4) aging the plate at the temperature of 120-130 DEG C; (5) testing the electric property of the plate after aging; (6) assembling the positive or negative plate for a qualified product and pressing fixing pins; (7) bending the connecting sheets on the positive or negative plate after assembly and laminating the connecting sheets together to form a circuit; and (8) testing a finished product to complete machining. By the aid of the machining method, defective machined products can be decreased, the frequency of mistaken assembly is reduced, and capacity is improved.
Description
Technical field
The present invention relates to a kind of processing method of auto rectifier.
Background technology
Auto rectifier is in process some defects due to lack of standardizationization that operates and in-house facility existence, make Chang Rongyi in its process the generation of misloading or various electrically bad and substandard product occur, make production efficiency reduce, and the waste of various resources and manpower, bring certain impact to Business Economic Benefit.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of processing method of auto rectifier, adopt this processing method, the product that processes can reduce bad product, reduces the frequency of misloading, improves production capacity.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of processing method of auto rectifier comprises the following steps:
(1), put brace on the sintering fixture, and smear soldering paste on brace, then tube core is placed on soldering paste;
(2), smear a soldering paste on the solder side of tube core, place positive plate or negative plate, advanced the stove sintering 10 minutes～20 minutes;
(3), after sintering completes, the mould of dismantling, come out of the stove and carry out appearance test, the underproof product screening of outward appearance fallen, and then carry out the pole plate test, electrical bad product screening fallen, until fraction defective is qualified;
(4), carried out the electrical bad product of rejecting aging 20 minutes～40 minutes at the temperature of 120 °～130 °;
(5), aging rear to electrically the testing of pole plate, filter for electrical bad product;
(6), qualified products are carried out the assembling of positive/negative plate, in the assembling positive/negative plate, with large support, positive/negative plate is fixed on together, on large support, corresponding installation site is arranged, can fix positive/negative plate, then small rack is arranged between positive/negative plate, presses solidly finally rationed marketing, make between positive/negative plate and small rack more fastening;
(7), assemble after, the brace on positive/negative plate is carried out bending, make the brace of positive/negative plate overlap together, form circuit;
(8), finished product is tested, procedure of processing is completed.
As a further improvement on the present invention, described ageing time is 25 minutes～35 minutes.
As a further improvement on the present invention, described ageing time is 30 minutes.
It is as a further improvement on the present invention, described that to advance the stove sintering time be 12 minutes～18 minutes.

(3), after sintering completes, the mould of dismantling, come out of the stove and carry out appearance test, the underproof product screening of outward appearance fallen, and then carry out the pole plate test, electrical bad product screening fallen, until fraction defective is qualified;
(4), carried out the electrical bad product of rejecting aging 30 minutes at the temperature of 120 °～130 °;
(5), aging rear to electrically the testing of pole plate, filter for electrical bad product;
(6), qualified products are carried out the assembling of positive/negative plate, in the assembling positive/negative plate, with large support, positive/negative plate is fixed on together, on large support, corresponding installation site is arranged, can fix positive/negative plate, then small rack is arranged between positive/negative plate, presses solidly finally rationed marketing, make between positive/negative plate and small rack more fastening;
(7), assemble after, the brace on positive/negative plate is carried out bending, make the brace of positive/negative plate overlap together, form circuit;
(8), finished product is tested, procedure of processing is completed.
The invention has the beneficial effects as follows: standardized work flow and processing method, greatly reduce the fraction defective of rectifier in process, standardization and normalized processing method and repeated detection, make the product fraction defective reduce, the utilization of steady pin and support, also reduce greatly its misloading rate, improved operating efficiency, also brought certain improvement for the economic benefit of enterprise.
